Question
Your team has used a data logger with graphing software to take data on the voltage across the capacitor in the series RLC circuit in the figures below.
The switch is set first to position
a, and the capacitor is charged.
The switch is thrown to
position b and oscillations begin.

Switch S has been at position a for a very long time and is then thrown to position b. You know that the capacitance C is 20.0 µF. Your data logger makes a graph of the voltage across the capacitor as a function of time, with t = 0 being the instant the
switch was thrown to position b. The graph is shown in the figures below.
